Compound water meter WPVR

Compound water meter with piston meter as secondary meter for use in drinking water distribution and industrial applications

The WPVR was designed to record fluctuating flows, for use in drinking water distribution and industrial
applications. The main meter is based on the proven Woltman parallel technology.

As a secondary meter a rotary piston meter is used, with which even small flows can be reliably recorded.
All materials, which are used in the drinking water section, comply with the required standards, guidelines and the current German drinking water approval (Other country-specific drinking water approvals on
request).
